To all whom t may cof/wem.'

Be it known that LAURENCE M.Foss, a citizen of the United States,residing at Amesbury, in the county of Essex and State of Massachusetts,have invented new and useful Improvements in Vindow-Operating Mechanism,of which the following is a specification.

This invention relates to mechanism for operating a sliding window,movable in guides in a frame, such as the hinged frame of the door of alimousine, or other vehicle body, said frame having an opening which maybe closed and opened by the sliding window, the window being closed byan upward movement.

The chief object of the invention is to provide mechanism adapted to bemanually operated by a minimum expenditure of muscular force in raisingthe window, and

adapted also toy maintain the window in any position to which it may bemoved, the mechanism being compactly'arranged and convenientlyinstalled. l

Other objects of the invention will appear hereinafter. y r

The invention is embodied in the improved mechanism hereinafterdescribed and claimed.` e.

0f the accompanying drawings forming a part of this specification,-

Figure 1 is a side elevation of a door, the window of which is fullyopened, the operating mechanism, excepting the crank- 35 shaft anditscrank hereinafter described,

being concealed by a facing board and the window being opened.` Figure 2is a similar view on a larger' I scale, the facing board beingremovedand 4@ a portion of the frame broken away.

Figure 3 is a view similar to Figure 2, showlng the window partiallyclosed, one position of the Window being shown by full lines, andanother by dotted lines.

Fi ure 4 is an enlargement of a.l portion of Figures 1, 2 and 3.

Figure 5 shows the' inner side of the p0rtion represented by Figure 4.

Figure 6 is a-section on line 6 6 of Fig 5@ ures l and 4.

Figure 7 is a section on line 7--7 of Figure 3.

Figure 8 is a section on line 8-8 of Figure 3.

Figure 9 is a -view similar to Figure 6, showing a modification.

The same reference characters indicate the same parts in all of thefigures. l

The frame,v designated as a whole by the reference numeral 12, may bethe hinged frame of the door of a limousine body, and may be of anysuitable construction providing upright guides 13, one of which is shownin section by Figure 8, for a sliding window. Said window may also be ofany suitable construction, and in this instance includes a glass pane14, and a mar-. gina-1 metal frame 14, the upright members of whichareslidable in the guides 13. The frame 12 has the usual opening 12a inits upper portion, and the window, when fully lowered, as shown byFigures 1 and 2, entirely exposes said opening, and when fully raised,covers the opening.

Fixed to the window, and preferably to the lower end member of the frame14a, is an inwardly projecting stud, which is substantially equidistantfrom the upright or guided edges of the window. Said stud is preferablycomposed of a fixed axle member or arm 16, attached to a fixed ear 17(Figure 7), on the window, and a grooved anti-friction roll 18,journaled to rotate freely on said arm.

19 represents a. traveller, here shown as an oblong metal plate, havinga longitudinal slot with opposed parallel pushing edges 20, contactingwith opposite sides of the periphery of the roll member 18, of thewindowstud. l et The traveller is connected with the frame by a pair 'ofparallel motion links 22 and 23, pivoted at 24 to a fixed ear or bracket25 on the frame, and at 26 to one end portion of the traveller, thearrangement being such that said links maintain the slot edges 20substantially at right angles with the path of movement of the window,and, when swung on their pivots 24, cause a combined endwise andedgewise movement we with the window stud.` L

I provide manually oper-able means for swinging said links in unison,and thereby causing the traveller to assume different positions, asindicated by Figures 2 and 3, and to slide the window in the frame.prefer to embody said means in a crankshaft 28, journaled infixedbearings on the frame, and provided with a pinion 29, and arack-bar meshing with the pinion and pivoted to the link 22. As hereshown, the rack-bar includes a toothed cuter section 30, and aninnersection 31, pivoted at 32 to the outer section, the sections beingconnected by screws 33. The bearings of the crank-shaft are preferablyformed in a circular plate 34, which is fixed to a cross-bar 35,attached to 4the frame 12, and in a strip 340 attached to and offsetfrom the plate 34. Said plate is insertedin a circular socket 36, in thecross-bar, and is provided with a marginal annular wall 37, seated onthe wall of said socket, and with an annular flange 38, seated on theouter side of the board. The plate 34 is offset from the outer side ofthe board, as shown by Figure 6, to

yform a recess for the operating crank,

whereby the shaft is rotated. Said crank is preferably f0ldable so thatit may be housed in said recess when not in use, as indicated by Figure4, and in part by dotted lines by Figure 6. The crank includes` an innersection 39, fixed to the shaft and located mainly in the recess formedby the plate 34and wall 37, and an outer section 40, which is forked atone end to bestride the section 39, and lis pivoted to the latter by a:pin 4l. When the crank is extended, as shown by full lines in Figure 6,the section 40 stands outside the cross-bar 35, so that its handle 42may be grasped by the operator. When the crank is folded, it Ienters therecessed plate 34, and its handle enters an orifice 43 in said plate, asshown by dotted lines, the crank being thus storedout of the way. Twohandle-receiving orifices 43 may be provided as vshown by Figure 4, topermit the folding of the crank in different angular positions.

A facing board` 45 (Figures l, 4 and 6) is secured to the frame 12 andt0 the cross-bar 35, and forms the inner side of the portion of thedoorvbelow the opening 12, as shown by Figurel 1, the cross-bar andtheentire mechanism above described, excepting the crank-shaft and itscrank,' being concealed by said facing board which, in a limousine door,may be surfaced with cloth to match the upholstery.

The facing board has a circularV opening 46, coinciding with the socket36y in the cross-bar. A ring 47 is nested in the wall portion 37 of theplate 34, and covers the Screws 49 secure the flanges 38 and 48 and' theintermediate portion of the facing board to the cross-bar.

The cross-bar'35 is cut away to `forni a n slot 50, extending throughits loweredge into the socket 36, and a recess 51 extending from saidsocket partly to the upper edge of the cross-bar. The rack-bar ismovable endwise in said slot, socket, and recess, and is held inengagement with the pinion 29 by a stud or roll 52. When the crank-shaftis rotated, the rack-bar swings the links 22 and 23 andthe travellerupward or downward, as the case may be. When the trav- .n

elleris full-y lowered, as shown by Figure 2, the window stud is in theouter end portion of the traveller slot, and the window is fully opened.When the traveller is raised, it is -at the same time moved endwise inthe direction of arrow a2, its slot edges sliding in contact with thewindow stud. When the links reach a substantially horizontal position',the window stud is at the inner end'portion 'of the traveller slot, asshown by Figure 3. When the links are swung further upward, the slotedges slidev in the opposite direction indicated by arrow y, Figure 3.

It will be seen that the slotted traveller is adapted to applywindow-raising or lowering pressure to a window stud which is midwaybetween the guided edges of the window, so that the window is evenlybalanced on the traveller, and the pressure of its guided eilges on theupright guides 13 is practically equalized, hence the window has notendency to bind on the guides, and is adapted to bel raised by aminimum expenditure of muscular force.

The pinion and rackconnbection betweenv the operating shaft and thelinks, is adapted to maintain the window, through the links, thetraveller, and the stud, in any position to which4 it may be raised orlowered To further minimize the force required to raise the window, Iprovide counterbalancf I prefer to give the link 22-a-somewhatl angularform, the lower edge thereof having a salient formation'. The link thusformed cooperates to better advantage with the spring-pressed arm 56than would be the case'if the link were straight.

l Figure 9 lshows a modification in which substitute for the plate 34,located within the socket 36, a plate 34a, attached to the outer side ofthe cross-bar and covering one end of the socket. The crank section 39is, in thisL case, entirely outside the cross-bar, but in view of thefact that the plate has the orifices y213, yeither 0f which is adaptedto receive the handle 42 of the section 40, the crank whe folded, doesnot project objectionably int the interior of the vehicle, the handlebeing stored inthe socketA 36 as before. The facing board is clampedaround its opening by a ring 48a, substituted for the Hange 48. v
